| Discuss The Viv Lab Rigid Arm please check. if you can trust the math it seems that putting the null at around 72-75mm will net the best overall compromise. Below is what 72mm looks like compared ot 99mm and a typical Lofgren A. dave | |
| Discuss The Viv Lab Rigid Arm Hey Lew.... Great job! Have you seen any mention in the documentation on where they want the null point to be placed? My guess is 2/3 to 3/4 the way to the leadout is a good start. dave | |
| Which SUT to match Koetsu Rosewood Standard in my system? @elliottbnewcombjr That is the MINIMUM signal strength it needs IN to boost the signal up to line level. does anybody have any documentation on this standard? As stated above it seems all technical but is 100% arbitrary since "Line Level" is... | |
| What is you tonearm’s Maximum Distortion? @rauliruegas Well, don’t tell to me but directly to the SAT designer. I do not have an issue where mark sets his null points and I do not believe he would fudge the inner groove radius to 75mm in the calculations to avoid showing the sharp in... | |
| What is you tonearm’s Maximum Distortion? @lewm I am skeptical in using the calculated number for anything other than crude relative comparisons and find the plots to be much more telling of the relationships at hand. Below are the plots for the table @optimize posted above. From looki... | |
| What is you tonearm’s Maximum Distortion? @rauliruegas It’s only a parameter manipulation Only a parameter manipulation??? If the parameter manipulation is kept hidden then there is another term for it. dave | |
| What is you tonearm’s Maximum Distortion? @optimize in order to enter your desired overhang and offset you need to tick the "custom" option or the program will calculate for the 'standard' alignment ticked. Also the number you enter into the initial arm length will autofill to the rema... | |
| What is you tonearm’s Maximum Distortion? @rauliruegas Since we are considering the theoretical, your proposed alignment simply looks like Löfgren A if you cheat the inner groove radius to 75mm and the outer groove to 143mm which is not realistic for all but the smallest selection of mu... | |
| What is you tonearm’s Maximum Distortion? @rauliruegas Forgot that if you want lower distotion figures then and using Löfgren A alignments its tonearm parameters set up are:overhang 21.58mm and offset angle 24.8°. Where the maximum error 0.94° maximum distortion 0.33% and ave... | |
| Discuss The Viv Lab Rigid Arm @maxson The less the underhang the closer the single null point will be to the runout groove. It is also important to pay attention to the cartridge zenith since a slight offset of the Zenith from 0° will have the same net effect as a slight ch... | |
| Discuss The Viv Lab Rigid Arm @rauliruegas As any can see it needed only most inner/outer groove radius and nothing else. This will give you the theoretical placement of the null points. Nobody is debating this. Again the topic at hand is actually placing those null poi... | |
| Discuss The Viv Lab Rigid Arm @rauliruegas for some reason you introduced this particular tangent in response to me simply mentioning in order to get two null points both overhang and offset are required. In this thread on feb 14 you wrote: Anyway, for me the VIV/underhun... | |
| Discuss The Viv Lab Rigid Arm @rauliruegas then please kindly explain to @dover how to use the null point formula you presented to set the two null points for the arm with zero offset. dave | |
| Discuss The Viv Lab Rigid Arm @rauliruegas specifying a formula and not understanding its relationship to the discussion at hand serves little good. I doubt Løfgren would suggest it possible to get two null points without the addition of overhang no matter how much you poin... | |
| Discuss The Viv Lab Rigid Arm @rauliruegas You have stripped all context from my original quote which was about the requirement of both overhang and offset to get two null points. Without overhang which requires an effective length to calculate the two null points cannot e... |
